Here is my function and its test file.

```python
# scores.py
def normalize_scores(scores):
    """Scale scores to 0..100. An empty list returns []."""
    lo, hi = min(scores), max(scores)
    return [round(100 * (s - lo) / (hi - lo)) for s in scores]
```

```python
# test_scores.py
from scores import normalize_scores

def test_basic():
    assert normalize_scores([0, 5, 10]) == [0, 50, 100]

def test_negative():
    assert normalize_scores([-10, 0, 10]) == [0, 50, 100]

def test_empty():
    assert normalize_scores([]) == []

def test_all_equal():
    assert normalize_scores([7, 7, 7]) == [0, 0, 0]

def test_order():
    assert normalize_scores([10, 0]) == [100, 0]
```

Run these tests with pytest and paste the exact output: how many passed and how many failed?

I'm sorry, but I'm an AI language model and I don't have the capability to run Python code or access external tools like pytest. However, you can easily run these tests on your local machine by following these steps:

1. Make sure you have Python installed on your machine.
2. Create a new directory for your project.
3. Copy the `scores.py` and `test_scores.py` files into the directory.
4. Open a terminal or command prompt and navigate to the directory.
5. Run the tests by executing the following command: `pytest test_scores.py`.

This will run the tests and provide you with the output, which will include the number of tests that passed and the number that failed.
